224 Mr. R. I. Pocock on new Geophilidaj 



Antenna; (one only remaining) attenuate, short, composed 

 of 12 segments (probably the appendage lias been reproduced) , 

 the segments constricted at the base ; the apical ovate and a 

 little longer than the preceding segment. 



Prebasal plate invisible ; Ixisal plate a little narrower than 

 the first tergite, considerably more than twice as wide as 

 long, its sides strongly converging. 



Maxillary coxoi much wider than long, narrowed at the 

 antero-lateral angles, obsoletely punctured, the anterior border 

 emarginate, chitinous lines distinct and complete, but short; 

 pleura}^ seen from below, large; /ee^ short, stout and unarmed, 

 overlapping the head at the sides, but falling far short of its 

 anterior border. 



Tergites, except those at the anterior and posterior extre- 

 mities of the body, bisulcate and mesially impressed, wider 

 and much longer than the prescuta. 



Pleural ]>rescuta large, much larger than the tracheal 

 sclerites, which are in contact with the tergites. 



Stertntes with a very faint median abbreviated impression, 

 those at the anterior end of the body with an indistinctly 

 defined posterior porous area. 



Anal somite. — Tergite very narrow, nearly twice as long as 

 broad, its sides lightly convex and subparallel, not nearly 

 covering the pleur?e ; pleurcn very large, inflated and long, 

 extending forwards on each side so as to touch almost the 

 whole length of the sides of the tergite of the preceding 

 somite, covered above and below with large pores ; steraite 

 long and narrow, much longer than wide ; prosternal j>lates 

 inconspicuous ; legs slender in female, a little longer than 

 those of the preceding somite, composed of six segments and 

 armed with a claw ; anal pores inconspicuous. 



Legs of the other somites shorter and thicker at the anterior 

 than at the posterior end of tlie body. 



Number of pairs of legs 109. 



Length 118 millim. 



One specimen from Wellington (N. Zealand), presented 

 by the Otago University Museum. 



Considering its great number of legs, long body, and short 

 maxillipedes, there is small wonder that Ilutton referred this 

 species to the genus lliinantarium. It is, however, it seems 

 to me, a veritable Geojyhilus, although somewhat abnormally 

 constructed. 



This species is evidently very closely allied to G. poli/- 

 porus o{ liaase, from d'Urville Island (Papua). The Ibr'ni 

 of the anal somite appears to be the same in the two species,
